  curl -s https://graphql.buildkite.com/v1 \

LAST_COMMIT=$(builds | builds_with_state "PASSED" | head -n 1)

FILES=$(git diff --name-only $LAST_COMMIT)

MATCH=functions*
for f in $FILES ; do
  if [[ $f == $MATCH ]]; then
    exit 0
  fi
done

exit 1

LAST_COMMIT = commit of last passed bulid
MATCH = in my case I want to exit successfully if something matches "functions" otherwise fail
